Application filed. March 25, 1910. Serial No. 551,536.

To all whom it may concern Be it known that I, SAMUEL S. VVILLIAM- SON,a citizen of the United States, residing at Philadelphia, in the countyof Philadel phia and State of Pennsylvania, have in vented a new anduseful Improvement in Non-Refilling Bottles, of which the following is aspecification.

My invention relates to a new and useful improvement in non refillablebottles and ha for its object to provide a simple and cheap constructionwhich while permitting the liquid to flow out of the bottle will preventany liquid from being forced into it.

In the accompanying drawings: Figure 1 is a section of a portion ofbottle showing my improvement applied thereto. Fig. 2, is a similar viewshowing the bottle inverted. Fig. 3, is a section at the line 3-3 ofFig. 1. Fig. 4:, is a detail section of the valve case and seat; andFig. 5, is a plan view of the valve.

In carrying out my invention as here embodied (A) represents a bottlehaving a short neck threaded at (B) and this neck has a beveled edge(0').

(D) is an attachable neck having screw threads in its lower end forengagement with the threads (B), and also having a groove (E) formedjust above the threads for the reception of a suitable cement. Thisgroove has depressions or corrugations (F) formed therein andcorresponding depressions (G) are formed upon the short neck so thatwhen the attachable neck is screwed into place the cement in the groove(E) will be forced into these depressions and when set this cement willlock the neck (D) against removal, as

will be readily understood.

(H) represents the valve case which is cylindrical, open at the top andhas the valve seat (1) formed in its bottom. This valve case fitsloosely in the neck (D).

(J) represents the keeper which rests on the top of the valve case andis held in place by the shoulder (K) formed on the inside of the neck(D) this keeper may be of any suitable design to prevent tampering withthe mechanism contained in the valve case, and in its under side isformed a conical recess (L) for the purpose which will hereinafterappear.

(M) represents the valve,the' lower end of which is conical to fit theconical seat (I) and both the seat and that portion of the valve whichfits therein should be ground to insure indicated at (0) only bind itmore tightly,

a perfect fit. Formed with the body of the valve are lugs (N) adapted toguide the valve in the case so as to cause it to move off or on its seatin an axial line only,which is of great importance in the successfuloperation of the device as hereafter shown. The top of the body of thevalve is conical as the angle thereof being less or nearer thehorizontal than the angle of the conical recess (L) and on the conicaltop (0) is placed a ball (P). As this ball is confined between theconical top (0) and the walls of the conical recess (L) it will I restin the wedge shaped space formed by the angles of the walls of the twocones and hold the valve upon its seat. The body of the valve ishollow'or of material which will float, so that should the bottle beinverted as shown in Fig. 2 any attempt to immerse it or force liquidupward therein will close the valve seat. The bottle may be tippedconsiderably without the ball releasing the valve, but should it betipped beyond a predetermined point, the ball will roll down the inclineof the conical recess (L) permitting the valve to slide open and thecontents of the bottle to fiow out.

In returning the bottle to its normal posi tion the ball will close thevalve before the bottle reaches a horizontal position thus cutting ofithe fiow of the liquid from the bottle but permitting any liquid in theneck to escape.

Many devices have been made which would prevent a bottle from beingrefilled by forcing liquid into the neck or by drawing a vacuum in thebottle, but little or no provision has been made for holding the valveon its seat when the bottle is subjected tovertical vibrations or asudden jar on the bottom, and such treatment will cause the ordinaryvalve to jump from its seat and permit the liquid to flow in. My deviceis therefore especially designed to prevent the refilling of a bottle bythese methods, which is accomplished by the ball being confined betweenthe surfaces (L) and (O) which are at such an angle to each other thatvertical vibration will tend to jam the ball into, the wedge shapedspace formed by these two surfaces, and from the further fact that thevalve is so guided that it must slide straight on an axial line, whilesuch a movement would crowd the ball sidewise andtherefore A cork orother suitable gasket (Q) is interposed between the inclined edge (0)and the'bottom of the be made of glass.

To make the bottle doubly secure againstrefilling I use a locking pin.(a) fitted to slide freely in a hole (2)) in the keeper, and this pinrests against the ball (P) when the bottle is in an upright position andremains in contact therewith till the bottle is tipped beyond thehorizontal when it will slide into the hole-and free the-ball. Thisconstruction has many advantages, one of which is that the ball ispositively locked against being jarred out of contact with the valve,and another advantage is the pin assists in crowding the ball into thewedge shaped space, thus more firmly pressing the valve on its seat.

Having thus described my invention whatv I claim isv 1. In anon-refilling device consisting of a buoyant valve, a valve seat towhich said valve is fitted, aball normally resting upon said valve, anda plunger fitted to slide in a straight line adapted to automaticallylock the ball upon the valve.

2; In a device of the character described, a valve casing, a buoyantvalve fitted to slide in said casing, a ball normally resting on the topof the valve, and a keeper fitted over the ball and a plunger fitted toslide in the keeper on the axial line of the valve and automaticallylock and unlock the ball by the change of position of the device.

3. In a non-refillable receptacle, the com-' bination of a valve seattherein, a valve adapted to co-act with said seat, a keeper mountedabove the valve straight bore in its vertical center open at its innerend, a plunger snugly fitted in said bore so as to move only on saidvertical cenand having a ter, and a ball disposed between the keeperwhen the bottle is and valve, and adapted to cooperate with the valveand plunger, I a

4. A .non refilling bottle comprising a body, a neck, a valve casesecured in said neck, a buoyant valve adapted to. close upon a valveseat formed .in the case, a keeper also secured in the neck and havinga" conical shaped recess formed in its under side, a ball adapted towedge in the space formed between the valve and keeper and a sliding pinmoving .in a straight axial line with the valve'adapted toautomatically,lock the ball in contact with the valve when the bottle is in certainpositions and release said ball in certain other positions.

v5. In a bottle, a non refilling device consistingot a .valve seat, avalve, a ball adapted to contact with said valve and a vertical Copiesof this patent maybe obtained for five cents each, by addressing theCommissioner of ratents,
